Diagnosis. Formulation by Wittmann (2018) amended in order to include previously unknown characters found in the below-described new species:

Diamysini with eyes normal, cornea well developed.Antennular peduncle terminally with the usual two flagella in both sexes, no accessory flagellum developed. Antennula with short to normal-sized appendix masculina (= male lobe), which is (measured without setae) always shorter than combined two terminal segments of antennular trunk. Antennal scale lanceolate, without spines, but setose all around, with distinct apical segment. Mandibles normal, palp 3-segmented, cutting edges with well-developed pars incisiva, lacinia mobilis, and pars molaris. Distal segment of maxillary palp with setae but without denticles. Thoracopods essentially normal, except that certain species show an oblique articulation between carpus and propodus in some of the endopods 3–8, and that certain species show dimorphic setal patterns on the carpus of endopod 5. Endopods 1–8 with unsegmented carpus, propodus, dactylus. As far as adult females are known, large oostegites on thoracopods 7, 8, none on thoracopod 6. All pleopods of females and pleopods 1–3, and 5, of males are vestigial, uniramous, unsegmented, setose. Male pleopod 4 modified, with distinct sympod, with unsegmented, setose endopod, and with (2–3)-segmented exopod, whereby the terminal segment ends in a large modified seta (plus additional smaller seta in certain species), remaining segments without setae. Uropods setose all around, without spines. Telson small, subtriangular to trapezoid, terminally truncate to distinctly emarginate; lateral margins with spines, latero-terminal edges each with one larger spine; terminal margin (between edges) smooth or armed with diverse cuticle structures.

Type species. Parvimysis bahamensis Brattegard, 1969 ; gender feminine.
